Knox (undisclosed) reverted to Minnesota's injured reserve list Friday, Aaron Wilson of KPRC 2 Houston reports.
Knox signed with the Vikings as an undrafted free agent in April and played in each of the team's first two preseason contests, totaling one catch (on three targets) for nine yards. The nature of his issue hasn't been disclosed, but he'll need to sit out the 2024 season unless he and Minnesota reach an injury settlement.
